C / C++
C
C is a general-purpose programming language created in 1972 by Dennis Ritchie. By design, C gives programmers relatively direct access to the features of typical CPU architectures, customized for the target instruction set. It has been and continues to be used to implement operating systems (especially kernels), device drivers, and protocol stacks, though its use in application software is decreasing. C is used on computers ranging from supercomputers to microcontrollers and embedded systems.
C++
C++ is a high-level, general-purpose programming language created by Danish computer scientist Bjarne Stroustrup. First released in 1985 as an extension of the C programming language, adding object-oriented (OOP) functionality and later expanding significantly with the addition of functional programming features. It supports low-level memory manipulation for systems like microcomputers and has been used for the creation and maintenance of Microsoft Windows. C++ has also added support for generic programming through the use of templates. It is usually implemented as a compiled language, and many vendors provide C++ compilers, including the Free Software Foundation, LLVM, Microsoft, Intel, Embarcadero, Oracle, and IBM.
